Blockchain Variants - Private

Another type of chain is private blockchains, also known as permissioned blockchains, which have several notable differences from public ones.

  1. Participants need consent to join the networks.
  2. Transactions are secret, and only ecosystem members granted permission to join the network have access to them.
  3. The centralized nature of private blockchains differs from that of public blockchains.

Enterprises that wish to cooperate and exchange data but don't want sensitive business data exposed on a public blockchain can use private blockchains. By their very nature, these chains are more centralized; the companies that operate them have a lot of influence over the members and governance systems. A private blockchain can or cannot be linked to a token.

How it works?
A private blockchain is a blockchain network that operates in a restricted context, such as a closed network, or is controlled by a single company. While it functions similarly to a public blockchain network in terms of peer-to-peer connectivity and decentralization, this blockchain is significantly smaller in scope. Rather than allowing everyone to join and donate processing power, private blockchains are generally run on a limited network within a corporation or organization. Permissioned blockchains and corporate blockchains are other names for them.

Advantages: The governing organization determines permission levels, security, authorizations, and accessibility. A business putting up a private blockchain network, for example, can choose which nodes have access to view, contribute, or edit data. It can also block some information from being accessed by third parties.
